Answer 1

In my case I had to uninstall babel 6

npm uninstall --save-dev babel-cli  babel-core babel-polyfill babel-preset-es2015 babel-preset-stage-2 babel-register

and then reinstall babel 7

npm i  --save-dev  @babel/cli  @babel/core @babel/node  @babel/polyfill  @babel/preset-env

and it worked for me.

Answer 2

I am able to fix this issue using below command

npm install @babel/core --save

Answer 3

Go in by running on Windows, %USERPROFILE%\.quokka

The ~/.quokka configuration is limited to the config.json file and any packages that exist in ~/quokka/node_modules.

Put the following into config.js,

{
  "pro":true, 
  "babel": {
    "presets": ["@babel/preset-env", " @babel/preset-react"],
    "plugins": [
      ["@babel/plugin-proposal-pipeline-operator", { "proposal": "minimal" }],
      ["@babel/plugin-proposal-decorators", { "legacy": true }],
      ["@babel/plugin-proposal-class-properties", { "loose": true }]
    ]
  }
}

Answer 4

babel-loader@8 requires Babel 7.x (the package '@babel/core'). If you'd like to use Babel 6.x ('babel-core'), you should install 'babel-loader@7'.

Answer 5

try to install npm install @babel/core --save if it does not work try to uninstall node_modules and reinstall

Answer 6

I've been dealing with this problem for a few hours and it mysteriously disappeared when I added a "devDependencies" section to my package.json file and moved the @types dependencies to it.
